This clinical trial tests how well dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) with standard clinical evaluation works to assess treatment response for patients with pancreatic cancer that may be able to be removed by surgery (borderline resectable). Borderline resectable pancreatic cancer (BRPC) is a certain type of pancreatic cancer that involves the arteries or veins near the pancreas. With the right treatment before surgery, it can be removed (resected) successfully. An MRI (magnetic resonance imaging) scan creates clear images of the structures inside the body using a large magnet, radio waves, and a computer. DCE-MRI can be used to calculate the blood perfusion. Blood perfusion can show disease status. Using DCE-MRI as part of standard clinical evaluation may provide a more accurate treatment response assessment for patients with BRPC.
